## Summary description

This is an 8-channel relay module (model EB638543327) operating at 5 V DC with maximum switching current 10 A per channel. Designed for control of multiple loads such as motors, lights, and appliances from microcontrollers, PLCs or manual switches. Provides isolated relay outputs, convenient screw or pin terminals, and is suitable for prototyping, automation projects and small installations.

## Long description

This 8-channel relay module operates at 5 V DC and provides eight isolated mechanical relay outputs with a maximum switching current of 10 A per channel. It is intended for controlling multiple loads such as DC and AC motors, lighting circuits, heating elements and household appliances from microcontrollers, PLCs, manual switches or other control sources. The module offers convenient screw terminal and pin header connections for input signals and output loads, making it suitable for prototyping, automation projects and compact installations.
Advantages
The relay module combines a compact footprint with individual channel isolation to reduce interference between circuits. Each channel uses a mechanical relay rated for up to 10 A, allowing direct switching of moderate power devices without additional driver relays. Screw terminals simplify wiring of loads and power, while pin headers support direct connection to development boards and microcontrollers. The 5 V DC coil rating matches common logic-level control signals and facilitates integration into low-voltage control systems.
Suitable for
 Home automation circuits and lighting control
 Prototyping with Arduino, Raspberry Pi and other microcontrollers
 Switching motors, pumps and small AC loads
 Laboratory test setups and control panels
 Small industrial or workshop automation tasks
Key specifications
 Number of channels: 8
 Coil (control) voltage: 5 V DC
 Maximum switching current per channel: 10 A
 Contact type: mechanical single-pole (SPST or SPDT depending on module wiring)
 Connection types: screw terminals for load outputs and power, pin headers for control inputs
 Isolation: separate relay contacts provide electrical isolation between control and load circuits
How to use
Power the module’s 5 V supply according to the module markings, connect control signals from the microcontroller or controller board to the corresponding input pins, and wire the loads to the relay output screw terminals following safety practices for the switched voltage. Verify polarity and appropriate power ratings before switching. When using microcontroller outputs that cannot source required coil current directly, use the module’s input drivers or an external transistor/driver stage as specified by the module documentation. Test each channel at low voltage first to confirm correct wiring before applying mains or high-power loads.
Usage recommendations
Ensure load currents do not exceed 10 A per channel and allow for inrush currents of motors or lamps when sizing circuits. Maintain proper spacing and insulation when wiring AC mains, use fuses or circuit breakers where appropriate, and follow local electrical codes. For noisy inductive loads, include appropriate suppression (snubber circuits or RC networks) if required to extend relay contact life.
